EPAs GHG Standards for Light-Duty Vehicles; Special Credits To Encourage PHEVs, BEVs and FCVs

Green Car Congress

Source: EPA. As part of its program, EPA is establishing a system of averaging, banking, and trading (ABT) of credits, based on a manufacturer’s fleet average CO 2 performance. Both EPA and NHTSA programs are footprint-based—i.e., g CO 2 /mi (EPA). mpg US (EPA). Light trucks. g CO 2 /mi (EPA).
